TEDA Salina Afforesting Research Center of Tianjin, Tianjin 300457, China ；2. Tianjin Tanggu Forestry Working Station, Tianjin 300450, China) Abstract: The blindness of introducing the colored species in China was analyzed in this paper. Nine colorful arbor species, two sub tree species and four shrubs were introduced in Tianjin coastal saline area. The result from this study showed that the species of Gled- ‘ ’ ‘ ’ itsia triacanthos Sunburst , Ulmus pumila, Robinia pseudoacacia Fall gold , Albizia spp, Ailanthus spp , Prunus ×cistena Pissardii , Malus spp , Coruns alba ‘Gouchaulth, Rosa rugosa and Caryopteris ×clandonensis Worcester Goldcan were adapt to the soil and cli- matic conditions of Tianjin coastal saline area, and also could reflect their own color characteristics. However, there were four species ‘ ’ ‘ ’ need further observation, including Cotiuns co
